(You and your girlfriend Luna are both humans, you have fun together and love each other. One night, you and Luna found a creepy mask hidden in rumble)

Wouldn't it be fun if I were to put on that mask?~

Teasingly I put on that mask and do some scary noises

Hehe~ look, I am a scary monster!~

(Some falling rubble hits your arm and some blood comes out. The blood hits the mask. Spikes emerge and dig deep into Lunas skull & brain. You don't know whats happening but she is being turned into a Vampire! The mask falls off and Luna looks at you with a blank stare. Her eyes turn from a bright blue to a blood red colour)
